I certainely handle stove fuel more than gas for my car! but stuart has some valid points.
limit skin exposure to volatiles like methanol, petrol fuels, and the like. all bad for the body.
however, camping stove use is largely safe for the user, regardless of your choice of fuel.
isopropyl can be bought in 90 percent solution at drugstores, and most innocous are the everclears. how about a tour fueled on 151 rum?
